Concrete work tool, method of making, and applications
First Claim
1. A concrete work tool in the form of a concrete float, comprising:
- an elongate float body characterized by a length dimension, L, and a width dimension, W, wherein L is equal to or greater than 2W, having a bottom surface,wherein at least a portion of the bottom surface has a curvilinear shape along a full lateral expanse of the width dimension,further wherein at least the portion of the bottom surface having the curvilinear shape is inclined with respect to a top surface of the float body along the length dimension, L, over a selected length towards at least one of a nose end and a tail end of the float body, such that the bottom surface of at least one of the nose end and the tail end has a three-dimensional shape.

Abstract
A concrete float body whose bottom (working) surface has a 3D shape/profile/contour over a nose region and a tail region of the float body. The nose region may be tapered across a width dimension of the float body. The tail region may be tapered across a width dimension of the float body. The nose and tail regions may have rounded corners. A perimetal edge of the float body may have a radius. The 3D surface may be produced by extruding, cutting from a solid material, die cast molding, or injection molding the float body wherein the bottom surface has a curvilinear shape along the width dimension, and monotonically decreasing a thickness dimension of the float body between the bottom surface and a top surface by removing material from the bottom surface.

9. A method for making a concrete work tool in the form of a concrete float, comprising:
-
providing an elongate float body characterized by a length dimension, L, and a width dimension, W, wherein L is equal to or greater than 2W, having a bottom surface, further wherein at least a portion of the bottom surface has a curvilinear shape along a full lateral expanse of the width dimension; and starting from a location no greater than a midpoint along the length dimension of the bottom surface towards at least one of a nose end and a tail end of the float body, monotonically inclining the bottom surface with respect to a top surface by decreasing a thickness dimension of at least a portion of the float body. - View Dependent Claims (10, 11, 12, 13, 14, 15)
